Ifund has a diverse portfolio of companies that contribute both positively and measurably to accelerate the transition in one or more focus areas; energy, food, water and resources.


BlueCity is located in the former subtropical swimming paradise Tropicana next to the Maas in Rotterdam and aims to accelerate the transition from an old, finite economy to a new, circular economy. BlueCity serves as an impact incubator for entrepreneurs by providing office space, workshops and laboratory space and fits in well with our activities.


Borg (formerly known as Summerheat) develops underground heat storage technology. This product allows single-family homes to store heated water for use when needed, using locally generated energy. Ifund has invested in Borg and played a direct role in the inception of the company.


Bundles offers subscriptions to high-quality white goods (washing machines, dishwashers, etc.) and other household items such as coffee machines and even beds. Ifund has provided multiple loans to the company, ​​paving the way for more regular financiers such as banks that are still looking for their role in the circular economy.


Chainable develops circular kitchens: every part can be replaced, refurbished and reused. In combination with a specialised material passport, the material loop in this sector can be closed to a great extent.

De Clique

De Clique offers a resource service for the CO2-neutral collection of separated organic waste flows (e.g. coffee grounds and orange peels) from companies, supermarkets, and hospitality facilities in urban areas. These waste flows are subsequently used to develop new products, such as bread, soap and beer.

De Streekboer

De Streekboer is working on a better, more sustainable, and fairer food system by realizing short and transparent food chains in the Northern Netherlands. Consumers can order fresh seasonal products directly from local farmers via its online platform, whereby the company ensures full transparency about the origin and impact of the products.


Foodlogica offers a sustainable solution for the last mile of food distribution in dense urban areas. They do this with electrically-assisted cargo bikes. Ifund has invested in Foodlogica because the company contributes to both the food and energy transition.


LOKOL is a vegan "fast-cuisine" chain that offers tasty and affordable meals. Ingredients are sourced locally, and the burger bun is even produced based on the principles of regenerative farming, together with Soil Heroes. Food waste is also minimised, resulting in a fully sustainable out-of-home experience for delicious plant-based food.


Kitepower develops innovative airborne wind energy (AWE) systems as a cost-efficient alternative for conventional wind turbines. With this technology, Kitepower hopes to revolutionise the off- and microgrid market, where energy generation via diesel is still ubiquitous. The product under development is the Falcon, a 100kW kite which is relatively easy to install and transport.


With their groundbreaking automated manufacturing method, New Fashion Factory (NEFFA, f.k.a. MycoTEX) enables fashion brands to produce their products locally and fully in 3D, using biofabricated materials. With this, the start-up offers a comprehensive solution for the current value chains in fashion, which are notoriously unsustainable.

New Optimist

New Optimist produces eco-conscious and circular streetwear in their Amsterdam-based atelier. The company wants to prove that circularity in the fashion industry is possible. Every piece of clothing is produced in such a way that it has a minimum impact on the environment, through for example the use of monomaterials, their repair service and deposit system.


Rechtstreex realises a transparent and local food chain by making products from the local food chain as accessible as possible for consumers willing to make conscious decisions in their purchasing of groceries. On the Rechtstreex platform, customers can order seasonal products directly with over 100 farmers and producers in the Rotterdam area.


Reliving develops an online platform for affordable vintage furniture. Via this curated marketplace, the company provides a second life to high-quality interior objects. In doing so, Reliving aims to counter the negative impact of the furniture industry, which has become particularly concerning with the recent rise of fast furniture.

ReSolved Technologies

ReSolved Technologies specializes in solvent-based recycling, offering a solution for the closed-loop recycling of engineering plastics and soft PVC from complex waste streams. The ReSolved technology involves selective dissolution of plastics followed by deep purification of the polymer solution including the removal of legacy additives, resulting in near-virgin quality recycled materials.

Tiny Library

Tiny Library is an online platform for the rental of a variety of baby gear. The products are offered via a 'Product-as-a-Service' model, thereby stimulating the broader transition from ownership to usage. Tiny Library gives a first-hand experience to second-hand items, thereby lowering the barrier for consumers to choose 'pre-loved' items.

Vet & Lazy

Vet & Lazy is a specialty beer brewery that brews the beer as circular as possible. They are experimenting with the influx of waste streams such as rainwater to use as ingredients. Because they work a lot with residual products, they fit in well with our vision of a sustainable food system and closing cycles.


ZonnepanelenDelen is a platform for solar energy, which enables anyone to participate in solar energy projects regardless of where they live. Participants receive an annual return based on the production of the solar energy project - the same principle as having the solar panels on your roof. With this project, the organization contributes to the energy transition whilst making it accessible to everyone.


Displayed below are the companies that were formerly part of our portfolio. For each of these, an exit event has taken place, such as a transfer of shares or the repayment of provided loans.

La Almendrehesa

La Almendrehesa commercialises organic almonds and other local products derived from the Altiplano Estepario, a region in Southern Spain. Within this region, La Almendrehesa fulfils an important role as a catalyst for regenerative farming, together with AlVelAl and Commonland.

Closing The Loop

Closing The Loop (CTL) offers phone users and sellers an easy solution to make their device material-neutral and waste-free by collecting discarded phones on behalf of customers and recycling them on a one-to-one basis. CTL fits within our focus area waste.

The Reclaimers

Through its subsidiaries De Dakdokters and Metropolder Company, The Reclaimers installs green roofs and develops, produces, and installs smart water retention roofs to remotely measure and control water storage on roofs. Like The Reclaimers, ifund sees rainwater as a raw material and not as a waste product.


Rotterzwam grows oyster mushrooms on coffee grounds and sells them to restaurants and supermarkets. Ifund has provided a loan because, like us, Rotterzwam believes in a society where cycles are closed by combining waste flows and food production.
